IVACHINE FOR JOINTING STAVES.

Specification of Letters Patent No. 23,514, dated April 5, 1859.

To all whom it may concern:

Be it known that I, JONATHAN TRoor, of Sinclairville, in the county of Chautauqua and State of New York, have invented a new and Improved Machine for Jointing Staves; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a front view of my invention. Fig. 2, a vertical section of ditto, taken in the line fc, Fig. l. Fig. 3, a horizontal section of ditto, taken in the line y, y, Fig. l.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of a rotary adjustable cutter wheel, and a vibrating' frame, provided with a clamp and form bed, and used in connect-ion with a gage and adjusting device, the whole being arranged as hereinafter fully shown and described, whereby staves of varying widths may be jointed very expeditiously and in a perfect manner.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a rectangular frame, which may be constructed in any proper way to support the working parts.

B, is a horizontal sliding shaft, which is fitted in the frame A, and on which a cutter wheel C, is placed, said wheel being provided with knives a, of chisel or plane form, the cutting edges projecting from one side of the wheel C. The front end of the shaft B, is connected with an arm o, the lower end of which is attached to a shaft D, at the front part of the frame A, said shaft having a treadle E, attached. To the back end of shaft B, a spring c, is attached, as plainly shown in Fig. 3.

On the upper and front part of the frame A, a frame F, is placed, said frame being fitted on a pintle d, at the center of its bottom and allowed to turn or vibrate freely on said pintle, see Fig. 2. This frame F, is formed of a sill c, two upright-s f, f, and cross piece y. The sill c, constitutes a formbed for the staves, the sill having its upper surface rounded or made convex corresponding to the curvature of the staves. lVithin' the frame F, and adjoining the inner sides of the uprights f, f, vertical bars lz, h, are placed and allowed to slide freely,

the upper parts of said bars passing through the cross piece g, and connected by a cross bar i, against which a spring j, bears, and the lower ends having guides 17X, attached which pass down into the ends of the sill or form-bed c, see more particularly Fig. l.

Between the two bars L, it, and near their upper parts a shaft 7c, is placed. lThis shaft has an arm Z, attached to each end of it, and to the end of each arm a bar m, is attached. These bars m, are pivoted near their centers to the inner sides of the bars 7L, 7L, the bars m, extending down as far as the bars L, at their junction with the guides z'x. To each bar it, a chain o, is attached, and these chains are connected at the lower ends with a shaft p, at the lower end of the front part of the frame A, the shaft y), being provided with a treadle Q.

To the upper part of the frame A, a horizontal board G, is attached. This board projects from the front side of the frame A, and a slide H, is fitted therein, and allowed to move freely. To the slide H, a spring I, is attached, the front end of said spring resting on the form bed e. To the slide H, two bars fr, r, are attached by links s, s. The bars r, r, project from opposite sides of the slide H, and are attached by pivots or screws z5, to the ends of horizontal bars u, a, that projectfrom the frame A. In each bar r, r, an adjustable block c, is placed, and through cach block a set screw a', passes.

The operation is as follows The attendant is seated at the front of the machine and has one foot on the treadle Q, the other on the trea dle E. The attendant lays a stave shown in red on the form-bed c, and by adjusting or turning the shaft 7c, actuates the bars m, the lower ends of which are in front of the stave, so that the stave will be perfectly par allel with the axis of the form-bed e. The treadle g, is then depressed and the bars 71., 7L, which were sustained or kept up above the form-bed by the spring j, are brought down and made to clamp the ends of the stave and press the same snugly down on the bed c. The end of the spring I, is then made to touch the outer side of the stave and by this means the bars r, r, are moved and the screws a', adjusted which govern or determine the movement or vibration of the frame A. The thicker the stave therefore the greater distance the slide H, will be thrown back and the more obliquely the frame F, allowed to turn. This will be understood by referring llt) to Fig. 3. tWhen the stave is thus adjusted on the form-bed e the attendant depresses the treadle E, and by that means actuates the shaft B, moving the cutter vvlieel C, which is rotated by any proper means, toward the edge of the stave, Which by adjusting or turning the frame F, first in one position and then the other, the screws a', determining such positions as previously stated, is jointed and a proper bilge given it. Then one side of the stave is ointed, its position is reversed on the form bed e, and the opposite Y side is acted upon precisely inthe same Way as the one described.

This invention is extremely simple andY ously used for similar or analogous purposes, but

Elaviu-g thus described my invention, what I do claim as new and desire to secure by Letters Patent, is Y l. The vibrating frame F, provided With the clamp bars L, It, and stave adjusting bars m, and used in connection with the 'gage screws ri, arranged substantially as shown for the purpose of properly presenting the staves to the cutters.

2. The combination of the above named parts with the rotating cutter Wheel C, arranged for joint operation, substantially as and for the purpose set forth.

JONATHAN TROOP.
